787641 divided by 80 
We're looking to find how many times 80 goes into 787641.

On to step 1:
The number 80 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 80

Advancing to step 2:
The number 80 fits into 78 0 times, leaving a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 78 leaves us with 78.
Grab the next digit (7) from the dividend, add it to 78, then carry on: 787 / 80

Advancing to step 3:
The number 80 fits into 787 9 times, leaving a remainder of 67.
The next digit of our result is 9. 
Result so far: 9.0
Subtracting 720 from 787 leaves us with 67.
Grab the next digit (6) from the dividend, add it to 67, then carry on: 676 / 80

Going ahead to step 4:
676 divided by 80 is 8 with a remainder of 36.
The number 8 becomes the next digit in our result. 
Result so far: 98.0
The remainder is 36 after subtracting 640 from 676.
Fetch the next digit (4) from the dividend, attach it to 36 and continue: 364 / 80

Step 5:
364 divided by 80 is 4 with a remainder of 44.
Write down 4 as next digit of the result. 
Result so far: 984.0
The remainder is 44 after subtracting 320 from 364.
Bring next digit (1) of the dividend behind the 44 and repeat the process: 441 / 80

On to step 6:
The number 80 fits into 441 5 times, leaving a remainder of 41.
The number 5 becomes the next digit in our result. 
Result so far: 9845.0
If we take 400 away from 441, we end up with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Step 7:
80 goes into 410 5 times with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 9845.5
If we subtract 400 from 410, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
The number 80 fits into 100 1 times, leaving a remainder of 20.
The next digit of our result is 1. 
Result so far: 9845.51
Subtracting 80 from 100 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 9:
200 divided by 80 is 2 with a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 9845.512
Deduct 160 from 200 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 10:
If we divide 400 by 80, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 9845.5125
If we take 400 away from 400, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 11:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 9845.5125
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 12:
0 divided by 80 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 9845.5125
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 9845.5125, and the remainder is 0.0.
